Spk: Yes, TransWarp GS support is planned.

With a bitmap_image_device you'd be able to provide a bmp image for the emulated device to capture. Waste of time or worthwhile?


Now you know: worthwhile smile

Thanks, I'm already looking at a couple of devices that will use this smile

I see you only do the conversion to m_a2_bitmap once in device_reset, so to scan multiple pictures you'd have to reset the machine between each picture. Is this an intentional limitation or an oversight?

Intentional to make a first version quickly that works and can get any other interested devs started. The image device itself will at least leak memory if you try to hotload a different picture right now so it's not a great idea.

ETA: And now I've fixed both of those things.

In double-hi-res with the 8-pass grayscale scan it doesn't do a half-bad job.

Would it be possible to enable MAME to capture the input of a USB webcam from the host machine?

Video input is planned but it'll require a lot of OSD-layer work. Since ComputerEyes is a slow scan device (it takes 6 seconds to do a full capture and you had to hold still for that time if you were using a video camera back in the day) "scanning" .PNGs seemed like a better solution.

When we emulate more capable stuff like the SGI Indy's live video input then having video in will be more useful.

Ah, I wasn't thinking about live video ... my webcam has a still image button, but of course you couldn't know that smile

How about things like the hand scanners (e.g. Logitech Scanman)?

AFAIK there's no consistent API for hand scanners, you might as well just scan to PNG.

Somehow I'm leaving the most important information out of my sentences today: For the handscanners I meant of course as emulated devices within MAME. Sorry for the chaos!
